BLM18KG221WH1D Frequently Asked Questions (FAQs)

  • The recommended land pattern for the BLM18KG221WH1D can be found in the Murata datasheet or in the IPC-7351 standard. It typically consists of a rectangular pad with a size of 3.5mm x 2.5mm, with a 0.5mm hole in the center for the inductor's terminal.
  • The BLM18KG221WH1D's temperature derating is specified in the datasheet. To handle it, you should ensure that the inductor's operating temperature is within the recommended range (typically -40°C to +125°C). If the operating temperature exceeds the recommended range, you should derate the inductor's current rating according to the datasheet's temperature derating curve.
  • The self-resonant frequency (SRF) of the BLM18KG221WH1D is not explicitly stated in the datasheet. However, it can be estimated using the inductor's inductance value and the parasitic capacitance. Typically, the SRF of a similar inductor is around 100-200 MHz. For a more accurate calculation, you can use an inductor modeling tool or consult with a Murata representative.
  • The BLM18KG221WH1D is a general-purpose inductor, and its frequency range is limited. While it can be used in high-frequency applications, its performance may degrade above 10-20 MHz. For high-frequency applications, it's recommended to use a high-frequency inductor specifically designed for that purpose, such as Murata's BLM series with a 'H' or 'F' suffix.
  • To ensure the BLM18KG221WH1D's reliability in a high-reliability application, follow the recommended storage and handling procedures, and ensure that the inductor is operated within its recommended specifications. Additionally, consider using a more reliable inductor, such as Murata's 'R' or 'P' series, which are designed for high-reliability applications.
